Two sources of sea-level pressure data were used to develop a valid pressure field for wave hindcasting purposes. The fundamental information was supplied by Meteorology International Inc. MII on a 63 by 63 grid covering the Norther Hemisphere. Supplemental data were taken from National Weather Service NWS synoptic surface charts. Comparisons of MII data and NWS data indicated that the MII data are incompatible with pressure measurements near storm systems therefore, the MII data were supplemented with NWS data in two specific areas. For storms within a specified area near the U.S. Atlantic coast, the pressure field was represented by NWS data in a fixed-area grid. For storms outside the fixed-area grid, the pressure field was reconstructed from MII data blended with NWS data. Author
